JONATHAN 7. SMITH, OF SHREVE, OHIO, ASSIGNOR OF ONEHALF TO NOAH A. WVALKER, OF FORT WAYNE, INDIANA.

, WATER-HEATER.

SPECIFICATION forming part of Letters Patent No. 650,801, dated May 29, 1900.

Application filed August 9, 1899.

To all whom it may concern:

Be it known that I, JONATHAN \V. SMITH, a citizen of the United States, residing at Shreve, in the county of Wayne and State of Ohio, have invented certain new and useful Improvements in Water-I Ieaters; and I do hereby declare that the following is a full, clear, and exact description of the same, ref erence being had to the annexed drawings, making a part of this specification, and to the figures of reference marked thereon, in which- Figure 1 is a perspective View showing parts broken away. Fig. 2 is a transverse section through line 00 as, Fig. 3. Fig. 3 is a longitudinal section.

The present invention has relation to water-heaters; and it consistsin the different parts and combination of parts hereinafter described, and particularly pointed out in the claim.

Similar numerals have reference to corresponding parts in all the figures of the drawings.

In the accompanying drawings, 1 represents the outer shell or jacket, which is substantially of the form shown in the drawings; but it is not absolutely necessary to provide the exact forin shown, inasmuch as the objects and purposes hereinafterdescribed can be carried out without any particular reference to the exact shape and size.

Within the jacket 1 is located the inner shell or wall 2, said inner wall 2 and jacket 1 being spaced one from the other, as illustrated in Fig. 2, and are so spaced for the purpose of producing a water-chamber located upon the sides and top of the heater or boiler proper.

It will be understood that in the construction of the heater proper tie-bolts should be provided, so as to hold the jacket 1 and the inner wall 2 in proper relative positions. At

and 2, and the positions of said ends being utilized for the purpose hereinafter described. At the ends of the plates 3 and 4. and the ends of the water-tubes 5 are located the waterchambers 6 and 7, the water-chamber 6 being extended downward at a point below the lower tier of tubes 5 and the said chamber being tapered toward its top or upper end. The water-chamber 7 is located substantially as shown in Figs. 1 and 3, and, as shown, said water-chamber is tapered toward its bottom or lower end, or, in other words, the water chambers 6 and 7 are tapered in .opposite directions, by which arrangement a better circulation of Water is produced.

For the purpose of providing a means for preventing the heat from going directly upward between the water-tubes the deflecting plate is provided, which deflecting-plate is formed of a width to correspond substantially with the width of the space between the in ner sides of the inner wall and extended to within a short distance of the rear end of the boiler proper.

It will be understood that a sufficient space, such as 9, should be provided for the purpose of producing a proper draft. I

The water is fed to the heater by means of a feed-pipe 10, said feed pipe being connected to asupply-pipe and the pipe 11 extended and connected at the bottom or lower end of the water-chamber 6, and when water is turned on it will find its way through the tubes 5 and into the chamber7 and also into the Waterchamber located between the inner and outer jackets or walls. From the top or upper end of the chamber 7 is eXtended the pipe 12, which pipe leads to proper heaters, and it will be understood that when more than one heater or radiator is used branches should be connected to the pipe 12 and lead to the heaters or radiators. When the water becomes heated in the heater proper, the heated water will ascend and the cold water descend, by which arrangement a circulation of water is brought about, and by locating the. tubes 5 as shown and the water-chambers 6 and 7 a better circulation is produced.

If in the event it is desired to out Oh. the Water from the chamber located between the jackets, the valve 13 is produced, said valve clined plates 3 and 4:, water-chambers 6 and 1 7 tapered in opposite directions inclined pipes connected to the parallel plates a supply 11 leading to the lower end or portion of chamher 6, the pipe 14 leading to the space between the jackets and provided with a valve, 1 5 and the pipe leading from the upper end or portion of thechamber 7, substantially as and for the purpose set forth.

In testimony that I claim the above I have 5' hereunto subscribed my name in the presence 20 of two v'vitnesses.

JONATHAN XV. SMITH.
